Date Apr. 25, 1985.Pneumatic mattress track system to be used as a construction element in vehicles. A soft air filled mattress formed for instance by mattress bags (5) is automatically rolled out and serves as running surface and means of propulsion. The hull (1) of the system is disposed over the mattress on an air cushion (4) and thus without mechanical friction. The mattress formed for instance by the mattress bags (5) is not air tight and filled once, but it is filled automatically when it runs under the system hull (1) and is kept under constant pressure in the carrying position. The air for the mattress is supplied from the air cushion (4) through inlet orifices (7) provided in the wall of the mattress facing the hull (1). The main area of use is transport in difficult and vulnerable terrain. |
